What I am going to tell now is one of my most absurd theories/ideas!!!
FACTS:
- Sirius tells to Harry in the Order of the Phoenix that James and Snape were always “at loggerheads”. After James started dating Lily too, there were at loggerheads, but not in front of Lily.
- The memory in the chapter "Snape's Worst Memory" is Snape's worst memory (obviously). Even though Snape doesn’t say that, JK has said.
- JK had said before the release of the Order of the Phoenix that we would come to know something very important about Lily in the 5th and the 7th books. We see Lily only in Snape's worst memory.
DEDUCTIONS:
- What we see about Lily in this memory is very important.
- It just couldn’t be one of those bad memories. JK is very particular about her “choice” of words which means it is indeed the “worst” memory. If James and Snape were always at loggerheads – fighting in front of everybody, then why should that particular memory be Snape's worst memory???? So WHAT is special in that memory which makes it "the worst"???(Till here everybody will agree I think)
- Other than James and co, there was someone else this time around – Lily. Is she that special person who made that memory “the worst”??? This can be the only possible reason (Some of you might not agree but this has to the reason, as JK has given lot of importance to Lily here and JK has made that memory Snape's worst memory, not a random bad memory)
REASONS:
Since Lily's presence mattered to Snape there, you need to consider her presence w.r.t Snape there i.e. what was the interaction b/w them? The interaction was – Lily supported Snape but that couldn’t have made that memory worse.
Snape called Lily a mudblood. Now could this be the reason??? There’s no other possible reason, is there??? (Not as far as I can see)
Snape might not have really minded calling her that then, but after a certain stage, I think he started loving her. Now I think he has this guilty conscious feeling. He thinks he is responsible to her death since he told the prophecy to Voldemort. He regrets to have called her a mudblood once, when she had come to his help. That feeling has made that memory “worst”.
It all depends on the character of a person with what you take as your “worst” memory/day/time. It may be the loss of someone you love. It may also be the time in which you didn’t realize the worthiness of that person and hurt him/her. It may be something else too. It just depends on your personality/character.
JK has said that Snape knows about “love” which makes him more “culpable” than Voldemort. I think he now regrets his "evil" doings and that’s why that memory “haunts” (a strange choice of word??) him.
I know I am going to get a lot of criticism and/or a lot of praise. Let it come. I will be pleased with whatever I get.
